Revision history for WWW::Mechanize::Plugin::JavaScript and ::DOM
0.009 27 February, 2009
The DOM plugin (0.011):
• Just doc fixes: The frame features are listed in ::Window,
and a previously fixed bug has been deleted from the list.
The JavaScript plugin:
• <!-- --> is supported in external JS libraries (RT #43582)
and in javascript: URLs.
• Trailing --> no longer requires // (RT #43582).
• Line numbers are now correct after a <!-- with multiple
line breaks before it.
0.008 23 January, 2009
The DOM plugin (0.010):
• Scripts that are sent with a transfer encoding (such as
gzip) now work.
• navigator->appVersion
• count_timers
The JavaScript plugin:
• check_timeouts has been removed.
JE backend (0.007):
•‘var x;’ now creates the global var instead of being a no-
op (broken in 0.006).
• Event handlers in an event attribute of a <form> element no
longer die when variables are named. (Thanks to Imre Rad
for alerting me to this.) (This was broken all the way back
in version 0.002.)
0.007a 18 October, 2008
The DOM plugin (0.009):
• The location object’s hash method now returns an empty
string when there is no fragment, instead of ‘#’ (with
warnings).
0.007 15 October, 2008
The DOM plugin (0.008):
• Modifications to comply with recent changes to LWP and Mech.
The JavaScript plugin:
• Likewise
0.006 25 September, 2008
The DOM plugin (0.007):
• The window object is now part of the event dispatch chain.
• The window method no longer dies when the page is not
HTML. As a result, you can now run JS code without an
HTML document.
• When a link in the DOM is clicked (via trigger_event or the
click method), it now goes to another page.
• It now provides Mech with handlers for extracting links and
images from the DOM.
• Scripts are properly decoded and are no longer always
treated as Latin 1.
• The DOM tree’s charset attribute is now set.
• The scripts_enabled method now disables event handlers as
well as <script>s.
• !doctype declarations are no longer dropped from the HTML
returned by Mech’s ‘content’ method.
• Frames (including inline frames) are now supported. The win-
dow object now has its ‘top’, ‘frames’ and ‘length’ meth-
ods; and you can use it as a hash or array to access frames.
• The document object now has its location object set. This
was broken in 0.005. (Thanks to David Williams for noticing
the bug.)
The JavaScript plugin:
• You can now specify custom functions for alert, etc., even
after the JS environment has been created.
JE back end:
• Methods returning window objects now work properly instead
of returning weird objects that die when you so much as look
at them.
• The global object can now be used as an array or hash to
access frames.
0.005a 7 September, 2008
The DOM plugin (0.006):
• The window object’s *_function methods (alert_function,
etc.) have been renamed to set_*_function, which is what
the docs already said; and they actually work now. As a
result, the corresponding options to the JavaScript plugin
now work again. (They were broken in the previous release.)
JE back end (0.005):
• Properties and methods that are supposed to return
DOMStrings can now return null. They used to return the
string ‘undefined’.
0.005 7 September, 2008
The DOM plugin:
• New scripts_enabled method for enabling/disabling scripts.
• The window object has been disentangled from the JavaScript
plugin and made its own Perl class, under the DOM namespace.
It is accessible via the ‘window’ method.
• This allows the window object to inherit
from HTML::DOM::EventTarget, which provides
addEventListener, onclick, etc.
• As a bonus, it has a ‘self’ method.
• The JS plugin’s check_timeouts method is now deprecated. Use
the DOM plugin’s new check_timers method instead.
The JavaScript plugin:
• Support for javascript: URLs
• The JavaScript back end’s constructor is now called with the
window object as its argument. It has to make the global
object delegate to the window.
JE back end (0.004):
• Modified to conform to the previous item. It does not yet
support wrapping global objects when they are passed to
other JS environments.
0.004 19 August, 2008
The DOM plugin:
• <body onload=...> now works.
• The DOM plugin can now be C<require>d without Mech already
loaded, so it works with tools like pmvers.
The JavaScript plugin:
• The location object now stringifies to its href property
instead of [object Location].
0.003 29 July, 2008
The DOM plugin:
• Event attribute handlers now receive URL and line
number info.
• On a page that has no Content-Script-Type header, a
script element with no language specified no longer
causes warnings.
• It used to be that, if multiple script elements or event
attributes used the same handler, and that handler was
passed to the plugin with a regexp to select it (as opposed
to 'default'), only every other script/event would be trig-
gered (forgot to clear a couple of hash iterators). This
has been fixed.
• $mech->content now returns the content in the encoding of
the page itself, rather than the encoding of the first page
encountered.
The JavaScript plugin:
• The engine method (experimental and undocumented--read the
source) has been added.
• clear_timeouts now actually works properly. It used to run
the code for each timeout only if the specified time had
*not* elapsed.
• Line numbers for event attributes are now passed to the back
end’s event2sub method.
JE back end:
• Read-only properties are now marked as such in the JS envi-
ronment (which prevents the setting of a property if a pro-
totype has a read-only property of the same name --the only
difference it makes) and now have their types (string, num-
ber, etc.) set properly.
• Class bindings now use JE’s ‘unwrap’ feature, so version
0.022 is now required.
• event2sub now supports line numbers.
0.002 23 December, 2007
The DOM plugin:
• The DOM plugin’s interface has changed. The callback rou-
tines passed to it now get a WWW::Mechanize object as their
first argument.
• Line numbers for inline scripts now work properly.
The JavaScript plugin:
• You can now set up class bindings before fetching the first
page (it used to die).
• CSS::DOM is now a prerequisite.
• setTimeout and clearTimeout have been added, along with the
check_timeouts plugin method.
• There is now a ‘screen’ object, but it has no properties.
You have to set them yourself with an ‘init’ call-
back routine.
• There is an ‘open’ method which simply moves to the next
page, ignoring all arguments except the first. It is just a
temporary placeholder.
• The navigator object now has an appName property, set to
WWW::Mechanize.
• Back-ends are now expected to accept a third argument to
new_function, indicating the return type (the JE binding
supports this of course :-).
• JavaScript code referenced in the page itself (as opposed to
code passed to the plugin’s eval method) used to be evalu-
ated in the same JS environment for all pages. This has
been fixed.
JE back end:
• JS event handlers for HTML elements now have the form in the
scope chain. (This applies to all elements that have a
‘form’ method.)
• JS event handlers now have the ‘this’ value set correctly.
0.001 24 November, 2007
First CPAN release
• The JavaScript plugin has been completely restructured. It
now supports multiple backends.
• It now allows one to provide an initialisation function that
is run whenever a JavaScript environment is created, as well
as custom alert, confirm and prompt functions.
• Allows binding of custom Perl classes via 'bind_classes'.
• The DOM plugin’s callback routines for fetching the page
content as HTML or text now check to see whether the page is
HTML first.
• The DOM plugin now overrides extract_forms.
• Started work on event-handling.
• A few other minor things
0.0.2 19 July, 2007
Updated ::DOM to work with a new patch for WWW::Mechanize
(modified according to Eric Wilhelm's suggestion)
0.0.1 17 July, 2007
A proof-of-concept sent to Andy Lester and to the LWP mailing
list. Requires a patch to WWW::Mechanize (also sent to
the list).
